The smallest possible Gatsby theme

Quick Start

mkdir my-site
cd my-site
yarn init
# install gatsby-theme-monomer and it's dependencies
yarn add gatsby react react-dom gatsby-theme-monomer

Then add the theme to your gatsby-config.js. We'll use the long form here for education purposes.

module.exports = {
  plugins: [
    {
      resolve: "gatsby-theme-monomer",
      options: {},
    },
  ],
}

That's it, you can now run your gatsby site using

yarn develop
